THE management of Metro Rail Transit 3 was forced to stop serving North Avenue in Quezon City to Shaw Boulevard in Mandaluyong City Monday afternoon because of a plastic material that was thrown into an electricity cable at the Ortigas Avenue Station.

At 3 pm the train system was only able to load and unload passengers only on Shaw Boulevard to Taft Avenue and vice versa while the management waited for the plastic material to be removed.

It wasn’t clear what plastic material had been thrown on the railways’ catenary system overhead, which officials said could have caused an accident.
